Unusual Cystic Acne, after trying Tretinion and fish oil pills

Hi, I really hope someone can give me some insight. I have never had acne before, just small whiteheads here and there that I used BP10% on each night and by the time I left for China at 24 I had no acne issues. Ever since moving here, I have started to get more small whiteheads on my forehead and chin. I stopped using BP because I couldn't find it here, I was only using salicylic wash and lotion (2%) which did nothing for a month.

I went to see a derm about this and she gave me Tretinion 1% and BP 5% (to apply at night and in the morning). In the first month I saw a great improvement and started taking fish oil pills to speed up recovery. Then suddenly after exfoliating (not supposed to on tretinion), the next morning I had two acne cysts! And I've never had a cyst in my life. This has continued with about 2 cysts a week for the past month and I'm completely helpless and scarred. I have a very public career and can't even leave my house at this point, I lose money every day. My derm said the cysts were not caused by Tretinion cream. She put me on Zithromax 500g/day for 6 days and 250g/day for another 6 days. I am seeing the cysts go down slightly but I can't afford accutane and someone like me shouldn't need it!!! My only thought is it may be the fish oil. I always have extremely oily skin. Sorry for the length of this but I have no REAL (valid, educated) medical opinions here and I feel really alone. Thanks.
